Citywide 30 km/h limits: balancing safety, flow and acceptance (Bologna)

Citywide 30 km/h limits sit at the intersection of safety, traffic flow and social acceptance—and Bologna offers timely insights. We outline a path that uses open data, structured listening and targeted adjustments to calibrate the perimeter and carve‑outs. The approach aims to lock‑in benefits while protecting vulnerable users, businesses and environmental goals. The guide details institutional and civic roles, evidence handling, tools to safeguard fairness and transparency, and how to translate outcomes into time‑bound, enforceable conditions. It includes examples, call and agenda templates, minutes models, operational checklists and quality indicators, plus guidance for clear communication, transparent timelines and the inclusion of vulnerable groups. Based on the Concorder proposal: citywide 30 km h limits balancing safety flow and acceptance bologna.
